    Course reviews

    • “
      MAP was a great introduction to the commercial side of the business for a health professional like myself. I am now able to identify and leverage synergies between my department and others in the organisation. Because of the diversity and calibre of its students, WBS has helped me increase my network and I have recommended MAP to a number of my colleagues. It was an investment worth more than the rand value of the course – and motivated me to do my MBA!

      Doing NMP with WBS has provided me with the basic and highly valuable skills as I prepare myself for a leadership role within my organisation. The programme had practical examples which I could relate to my real situation at work.
